186 BRAZILIAN DERMAPTERA AND ORTHOPTERA 



FORFICULIDAE 



Doru lineare (Eschscholtz) 



1S22. Forficida linearis Eschscholtz, Entomographien, p. 81. [Santa Catha- 

 rina, Brazil.] 



Sao Paulo, State of Sao Paulo. February 1; garden field. 

 Two males. 



These specimens are true lineare in the relative length of the 

 pygidial spine and the curve of the branches of the forceps when 

 seen in lateral aspect, but the wings do not extend distad of the 

 tegmina, in this resembling the North American aculeatum. This 

 is the first demonstration we have had of the presence of intra- 

 specific wing dimorphism, such as we find in Psalis and Labidura, 

 in this genus. In consequence the key to certain species of this 

 genus recently published by Rehn and Hebard^ will require some 

 modification, the presence or absence of exposed portions of the 

 wings not being a valid diagnostic character and therefore it 

 should be eliminated from the key. The other features given 

 are, however, of prime importance. 



Doru luteipenne (Serville) 



1839. Forficula ?Mto'penms Serville, Hist. Nat. Ins., Orthopt., p. 46. [Brazil.] 



Piassaguera, State of Sao Paulo. October, 1910. (H. Liider- 

 waldt.) Two males. 



This is the first opportunity we have had to examine this strik- 

 ing species, which has generally been considered to be a synonym 

 or but a variety of lineare. It is in fact a very distinct species, 

 separated from lineare and aculeatum by the heavier sculpture of 

 the abdomen, particularly of the disto-dorsal segment of the 

 same, and by the elongate limbs, the tarsi, especially, being much 

 more elongate. In addition, the position of the tooth on the 

 internal margin of the male forceps is median instead of distad as 

 in lineare.
